:word: From what I've heard, the 4l60e was pretty closely designed around the Dex III fluid, which to me makes it a bad idea to switch to something with different properties.Hit Man X said:I still have set to see the need for syn trans fluid, I use the cheapo Dex III and change it every 10K... trans works great and has nearly 80K mi with no TqMgt present.
That money is better spent elsewhere IMO.
